I've put my own custom inlet on my s2 with 2.5 inch charge pipe and new grs, it's running real lean, it's a 90spec. on my meter unit there is a black box and a grey box on the side, which 1 has the 3mm hex key inside, I was going to jam an emission tester up the exhaust and give it a quarter turn, see if it helps any advice appreciated.
